Three-dimensional (3D) high-definition endoscopy is an innovative technical advancement that helps surgeons gain precise depth perception and spatial recognition during endoscopic surgery. Here, we describe a new dual optical channel 3D neuroendoscopic technique and its clinical application. We performed endoscopic endonasal surgery on 88 patients using 3D and two-dimensional (2D) endoscopes in conjunction. We evaluated the usefulness of stereoscopic images acquired by dual optical channel 3D endoscopy during endoscopic surgery and compared the image resolution between dual optical channel 3D endoscopy and 2D endoscopy. Additionally, we compared the stereoscopic images acquired by dual optical channel and Visionsense 3D endoscopy in three cases. Combination surgery using 3D and 2D endoscopy was found to be safe. Stereoscopic images were useful in several surgical steps, especially in recognition of complex bony structures, bone drilling, and suprasellar manipulation. The magnitude of binocular disparity was greater in dual optical channel 3D endoscopy than in Visionsense 3D endoscopy. Stereoscopic images acquired by dual optical channel 3D neuroendoscopy were of adequate quality and were useful for endoscopic endonasal surgery. In consideration of its lower image resolution compared to that of 2D high-definition endoscopy, dual optical channel 3D neuroendoscopy can be applied as an assistive technique in endoscopic endonasal surgery. The magnitude of binocular disparity is one of the key factors to be considered for evaluation of the clinical significance of 3D endoscopy.
